## Which problem is this PR solving? ## Short description of the changes This PR replaces `os.Setenv` with `t.Setenv`. Starting from Go 1.17, we can use `t.Setenv` to set environment variable in test. The environment variable is automatically restored to its original value when the test and all its subtests complete. This ensures that each test does not start with leftover environment variables from previous completed tests. Reference: https://pkg.go.dev/testing#T.Setenv ```go func TestFoo(t *testing.T) { // before os.Setenv(key, "new value") defer os.Unsetenv(key) // after t.Setenv(key, "new value") } ``` Signed-off-by: Eng Zer Jun <engzerjun@gmail.com>
